我根据教程使用NandFlash上的u-boot烧写NorFlash/， u-boot也是采用 u-boot_burn_nor_with_nand.bin 文件。步骤如下
- 将u-boot_burn_nor_with_nand.bin写入nand
- 选择nand引导按钮，并且开机。
- u-boot启动后，把按钮退回nor启动
- 在u-boot menu中，选择rescan nor
- 选择“copy bootloader from nand to nor“
结果：
reading NAND page at offset 0x0 failed
Could not read entire image due to bad blocks
尝试nor启动u-boot失败。
以下附详细过程，恳请帮助。
